Technically this is three handwaves, but it gives you a "reactionless" total conversion drive (i.e. no noticeable exhaust) that is inefficient as a power plant.

That does seem imply pretty efficient power plants. You just chain the ship to an enormous turbine. Planets, but maybe not most ships, with access to it end up with a huge source of energy.
